Description

Technical Field

[0001] This utility model relates to the field of cable production equipment technology, and in particular to a cable stranding machine. Background Technology

[0002] A cable stranding machine is a device that can twist multiple wires into a single strand. During the stranding process, the stranding machine needs to bend and transport the wires. As the wires enter the stranding reel from the wire roller and then enter the stranding die, they will rub against the guide wheel, the through holes on the stranding reel, and the stranding die, generating unstable resistance, which will cause the wires to wear and, in severe cases, even break.

[0003] In the prior art, the invention patent with publication number CN119049806A provides a cable stranding device for cable production, including a stranding machine with a stranding reel and a stranding mold. This invention, through the arrangement of a mounting frame, a second roller, and a warning light, utilizes the second roller to compress the stranded wire, reducing the bending angle of the stranded wire. The first roller adjusts the angle between the stranded wire and the through-hole on the stranding reel, allowing the stranded wire to pass parallel to the through-hole. This reduces friction between the stranded wire and the stranding mold and reel, reducing wear and debris generation. When a stranded wire breaks, it is no longer taut. The compressed auxiliary spring releases and pushes the mounting frame to move. The moving mounting frame compresses and triggers a switch, activating the warning light at the corresponding position. The warning light illuminates to alert workers of the breakage, allowing for timely detection and machine shutdown for adjustment.

[0004] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems: the design in the patented technology can only reduce the bending angle of the stranded wire (conductor). The conductor will still be subject to the frictional resistance of the guide wheel and the stranding disc during the stranding process, and there is still a possibility of wear and breakage. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by developing a cable stranding machine that eliminates the need to bend the conductors during the stranding process, thereby minimizing conductor wear and breakage.

[0006] The technical solution to the technical problem solved by this utility model is as follows: An embodiment of this utility model provides a cable stranding machine, including a base plate, a stranding device, and a stranding mold. The stranding device and the stranding mold are respectively installed at the front and rear ends along the length of the base plate. The stranding device includes a column, a feed roller, a wire frame, a rotating shaft, and a motor. Multiple columns are arranged parallel to each other along the length of the base plate, and the columns are vertically arranged. One rotating shaft is installed on each column via bearings. The wire frame is arranged between two columns, and a rotating shaft is connected to each end of the wire frame. The feed roller is installed on the wire frame via bearings and is perpendicular to the wire frame. The motor is installed on the frontmost column, and the output shaft of the motor is connected to the rotating shaft. The rotating shaft is hollow. A through hole is provided at each end of the wire frame, and the through hole is concentric with the rotating shaft. The stranding mold includes a vertical plate and a base. The vertical plate is installed on the base plate via the base. The vertical plate has a wire-passing hole corresponding to the cable diameter, and the wire-passing hole is concentric with the rotating shaft. The wire-passing hole is a round hole, and its diameter is larger than the cable diameter. Multiple independent wires converge in the wire-passing hole. All wire frames and shafts are fixed as a whole. When the motor drives the wire frames and shafts to rotate, the wires on the pay-off rollers rotate accordingly, forming a twisting action, and the twisting is completed in the wire hole.

[0007] As an optimization, the stranding device also includes reinforcing plates, one on each side of the outer side of the wire frame, with each end of the reinforcing plate connected to a pivot at one end of the wire frame. The reinforcing plates improve the connection strength between adjacent pivots.

[0008] As an optimization, at least three columns are provided, and at least two sets of wire feeding rollers and wire frames are provided.

[0009] As an optimization, the stranding die also includes a pressure plate, an adjusting rod, a spring, and an adjusting wheel. The wire passage hole is an elongated hole with an opening at the top. The pressure plate is set on the top of the upright plate. One end of the pressure plate is connected to the upright plate through a rotating shaft, and the other end of the pressure plate has an opening. The adjusting rod is a threaded rod, and the adjusting wheel has a threaded hole corresponding to the adjusting rod. The lower end of the adjusting rod is connected to the upright plate through a rotating shaft, and the upper end of the adjusting rod passes through the opening on the pressure plate and connects to the adjusting wheel. The spring is set on the adjusting rod between the adjusting wheel and the top surface of the pressure plate.

[0010] As an optimization, the width of the through hole is greater than the diameter of the cable.

[0011] As an optimization, the cable stranding machine also includes a guide, which is located at the rear end of the stranding die. The guide includes pressure rollers and mounting plates. Two parallel mounting plates are vertically arranged, and two pressure rollers are arranged, one above the other. The two ends of the pressure rollers are mounted on the two mounting plates via bearings, with the two pressure rollers in contact. Arc-shaped guide grooves are provided on the outer sides of the two pressure rollers. The cable passes through the guide grooves between the two pressure rollers. By using the guide, the direction of the cable can be further corrected, facilitating subsequent cable winding.

[0012] As an optimization, the cable stranding machine also includes a take-up device, which is located at the rear end of the guide. The take-up device includes a take-up roller, a fixed frame, and a second motor. The two ends of the take-up roller are mounted on the fixed frame through bearings. The second motor is mounted on the fixed frame, and the output shaft of the second motor is connected to the take-up roller.

[0013] As an optimization, the top surface of the take-up roller, the contact surface of the two pressure rollers, and the center of the wire-passing hole are flush.

[0014] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0015] 1. This cable stranding machine eliminates the traditional stranding reel. All the wires to be stranded enter the through hole, the center hole of the rotating shaft, and the wire passage hole on the stranding die directly from the pay-off roller. Since the through hole, rotating shaft, and wire passage hole are concentric, there is no need to bend the wires during the stranding process, which minimizes the wear and breakage of the wires.

[0016] 2. By setting the cable passage hole as an elongated hole with an opening at the top, the cable can float up and down in the cable passage hole. The pressure of the pressure plate on the cable can be adjusted by rotating the adjusting wheel, which can minimize the friction on the cable.

[0017] 3. By setting the top surface of the take-up roller, the contact surface of the two pressure rollers, and the center of the wire passage hole to be flush, bending of the wires during the twisting process into cables can be avoided, thus preventing wear or breakage of the wires.

Detailed Implementation

[0027] To clearly illustrate the technical features of this solution, the invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0028] Figures 1 to 8 As one embodiment of this utility model, such as Figure 1 As shown, a cable stranding machine includes a base plate 1, a strander 2, a stranding mold 3, a guide 4, and a take-up device 5. The strander 2 and the stranding mold 3 are respectively installed at the front and rear ends of the base plate 1 along its length. The guide 4 is located at the rear end of the stranding mold 3, and the take-up device 5 is located at the rear end of the guide 4.

[0029] like Figures 2 to 4 As shown, the stranding device 2 includes columns 21, a feed roller 22, a wire frame 23, a reinforcing plate 24, a rotating shaft 25, and a motor 26. Multiple parallel columns 21 are arranged along the length of the base plate 1, and the columns 21 are vertically arranged. One rotating shaft 25 is mounted on each column 21 via bearings. The wire frame 23 is positioned between two columns 21, with a rotating shaft 25 connected to each end of the wire frame 23. The feed roller 22 is mounted on the wire frame 23 via bearings. The feed roller 22 and the wire frame 26 are connected... 3. Vertically, motor 26 is mounted on the foremost column 21. The output shaft of motor 26 is connected to a rotating shaft 25, which is hollow. A through hole 231 is provided at each end of the wire frame 23, and the through hole 231 is concentric with the rotating shaft 25. The stranding mold 3 includes a vertical plate 31 and a base 36. The vertical plate 31 is mounted on the base plate 1 via the base 36. The vertical plate 31 has a wire-passing hole 311 corresponding to the cable diameter, and the wire-passing hole 311 is concentric with the rotating shaft 25. A reinforcing plate 24 is provided on each of the outer sides of the wire frame 23, and both ends of the reinforcing plate 24 are connected to the rotating shafts 25 at both ends of the wire frame 23. The reinforcing plate 24 improves the connection strength between adjacent rotating shafts 25. Multiple independent wires converge in the wire-passing hole 311. All wire frames 23 and rotating shafts 25 are fixed as a whole. When the motor 26 drives the wire frames 23 and rotating shafts 25 to rotate, the wires on the wire feeding roller 22 rotate accordingly, forming a twisting action, and the twisting is completed in the wire hole 311.

[0030] like Figure 1As shown, seven columns 21 are provided, and six sets of wire feeding rollers 22 and wire frames 23 are provided. This allows for the twisting of six strands of wire.

[0031] like Figure 5 , Figure 6 As shown, the stranding mold 3 also includes a pressure plate 32, an adjusting rod 33, a spring 34, and an adjusting wheel 35. The wire passage hole 311 is an elongated hole with an open top. The pressure plate 32 is located on the top of the upright plate 31. One end of the pressure plate 32 is connected to the upright plate 31 via a rotating shaft, and the other end of the pressure plate 32 has an opening. The adjusting rod 33 is a threaded rod, and the adjusting wheel 35 has a threaded hole corresponding to the adjusting rod 33. The lower end of the adjusting rod 33 is connected to the upright plate 31 via a rotating shaft, and the upper end of the adjusting rod 33 passes through the opening on the pressure plate 32 and connects to the adjusting wheel 35. The spring 34 is located on the adjusting rod 33 between the adjusting wheel 35 and the top surface of the pressure plate 32. The width of the wire passage hole 311 is greater than the diameter of the cable. By setting the wire passage hole 311 to be an elongated hole with an open top, the cable can float up and down in the wire passage hole 311. The pressure of the pressure plate 32 on the cable can be adjusted by rotating the adjusting wheel 35, which can minimize the friction on the cable.

[0032] like Figure 7 As shown, the guide 4 includes pressure rollers 41 and mounting plates 42. Two parallel mounting plates 42 are vertically arranged. Two pressure rollers 41 are arranged, one above the other. The two ends of the pressure rollers 41 are mounted on the two mounting plates 42 via bearings, with the two pressure rollers 41 in contact. An arc-shaped guide groove is provided on the outer side of each pressure roller 41. The cable passes through the guide groove between the two pressure rollers 41. By using the guide 4, the direction of the cable can be further corrected, facilitating subsequent cable winding.

[0033] like Figure 8 As shown, the take-up device 5 includes a take-up roller 51, a fixed frame 52, and a second motor 53. The two ends of the take-up roller 51 are mounted on the fixed frame 52 via bearings. The second motor 53 is mounted on the fixed frame 52, and its output shaft is connected to the take-up roller 51. The top surface of the take-up roller 51, the contact surfaces of the two pressure rollers 41, and the center of the wire passage hole 311 are flush. By ensuring that the top surface of the take-up roller 51, the contact surfaces of the two pressure rollers 41, and the center of the wire passage hole 311 are flush, bending during the stranding of the wires into a cable can be avoided, preventing wear or breakage of the wires.

[0034] This cable stranding machine eliminates the traditional stranding reel. All the wires to be stranded enter the through hole 231, the center hole of the rotating shaft 25, and the wire passage hole 311 on the stranding die 3 directly from the pay-off roller 22. Since the through hole 231, the rotating shaft 25, and the wire passage hole 311 are concentric, there is no need to bend the wires during the stranding process, which minimizes the wear and breakage of the wires.

[0035] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
